Definitions
- AD Alzheimer's disease
- a leading cause of dementia develops in one percent of the population between the ages 65 and 69, and increasing to 40-50% in those 95 years and older.
- AD patients exhibit telltale clinical symptoms that include cognitive impairment and deficits in memory function.
- heavy senile plaque burden found in the cerebral cortex verified by post mortem histopathological examination, confirms the presence of AD.
- the mature senile plaques consist of intracellular neurofibrillary tangles (NFT) derived from filaments of hyperphosphorylated tau proteins, and extracellular ⁇ -amyloid peptides derived from enzymatic processing of amyloid precursor protein.
- NFT neurofibrillary tangles
- ⁇ -amyloid peptides derived from enzymatic processing of amyloid precursor protein.
- Alzheimer's disease being the fourth leading cause of death in the United States
- pharmaceutical intervention has yet to commercialize a curative therapy.
- clinicians currently prescribe cholinesterase inhibitors to cognitively impaired patients.
- Rivastigmine a therapeutic treatment for both AD and Parkinson disease patients, inhibits both acetylcholinesterase and butyrylcholinesterase, preventing the breakdown of acetyl- and butyrylcholine.
- Galantamine a naturally derived acetylcholinesterase inhibitor, increases nicotinic cholinergic receptors to release acetylcholine into the brain.
- the acetylcholinesterase inhibitor Aricept slows progression of AD in patients by inhibiting acetylcholinesterase and thus increasing cortical acetylcholine.
- Aricept's effectiveness slowed AD progression in patients but the therapeutic effects disappeared after 36 months.
- the effect of treating AD patients with a therapeutic combination of both Aricept and memantine caused an increased cognitive function in those AD patients relative to those who just received only Aricept.
- the current array of AD therapeutics can only delay full-onset AD by approximately two to three years, after which they are therapeutically ineffective in inhibiting cognitive decline. It has been reported that delaying AD onset by five years is sufficient to reduce the number of AD cases in half and, given the current shortcomings of cholinesterase inhibitors, further research efforts are required to meet that goal.
- AD precursors As summarized from a recent discussion group on Dec. 5, 2006, (Biochemical Pharmacology Discussion Group, cosponsored by the American Chemical Society's New York section), researchers are now focusing on methods that target AD precursors by blocking either ⁇ -amyloid protein (BAP) production or by controlling mutant tau protein formation. Clearly, this focused research effort aims to control the formation of AD precursors that potentially lead to AD and this new strategy might delay full-onset AD more effectively that current therapeutics. In parallel, neurological imaging must mirror the therapeutic trend by identifying AD precursors in a duel effort to compliment both AD therapeutic development and, in addition, identify presymptomatic at-risk AD patients.

- PET and SPECT utilize radiolabeled compounds
- PET and SPECT are very sensitive techniques and require small quantities of radiolabeled compounds, called tracers.
- the labeled compounds are transported, accumulated and converted in vivo in exactly the same way as the corresponding non-radioactively compound.
- Tracers, or probes can be radiolabeled with a radionuclide useful for PET imaging, such as 11 C, 13 N, 15 O, 18 F, 64 Cu and 124 I, or with a radionuclide useful for SPECT imaging, such as 99 Tc, 77 Br, 61 Cu, 153 Gd, 123 I, 125 I, 131 I and 32 P.
- PET creates images based on the distribution of molecular imaging tracers carrying positron-emitting isotopes in the tissue of the patient.
- the PET method has the potential to detect malfunction on a cellular level in the investigated tissues or organs.
- PET has been used in clinical oncology, such as for the imaging of tumors and metastases, and has been used for diagnosis of certain brain diseases, as well as mapping brain and heart function.
- SPECT can be used to complement any gamma imaging study, where a true 3D representation can be helpful, for example, imaging tumor, infection (leukocyte), thyroid or bones.

(white solid, 22 mg, 12%).

- CB-001 has a slightly higher c Log P than FDDNP (3.8 vs 3.4) and would be expected to have poorer washout than FDDNP based on these values. However, despite the difference in c Log P values, CB-001 has a lower non-specific binding propensity and displays a much better grey to white matter ratio compared to FDDNP (see section above, “original wash”).
- the white matter binding of FDDNP is several shades darker than CB-001's white matter binding, indicating low non-specific binding of CB-001.
- F-PiB which has a c Log P value of 3.99, also displays reasonable, binding ratios similar to CB-001, albeit displaying a very weak overall signal.
- the washing data suggests that the carbazoles are a viable and novel target for imaging AD-related targets due to their unique binding and washout properties.
- CB-003 a tracer with a c Log P value similar to FDDNP, was prepared and tested. Using washing conditions that were far milder than the harsh washing conditions ( FIG. 9 ), CB-003 displayed excellent grey to white matter binding ratios that are far superior to the results taken from FDDNP, PiB and CB-001. These favorable and unique results suggest that CB-003 would have a more favorable brain washout in living systems, leading to more specific uptake and lowered non-specific binding, leading to a clear advantage over FDDNP and PiB imaging.
- CB-003 was used to clearly differentiate between a healthy brain and an AD brain ( FIG. 10 ). More specifically, by using the mild wash protocol, the amyloid deposits were clearly visible in the grey matter with little white matter uptake. The results were corroborated by both antibody IHC and thioflaving T amyloid staining, confirming the specificity of uptake. These surprising results demonstrate that this tracer possess the unique quality of rapid washout from white matter and significant high uptake in grey matter that is specific for AD plaques.
- the carbazole series also demonstrated a unique and surprising ability to bind favorably and preferentially to insoluble aggregates (9 nM) over soluble aggregates (262 nM) ( FIG. 12 and FIG. 13 ).
- PiB also binds well to insoluble aggregates (16 nM) but also binds essentially equally as well to soluble aggregates (48 nM) ( FIG. 14 and FIG. 15 ).
- CB-003 provides a larger binding ratio of 29:1, whereas PiB only provides a ratio 3:1.
- CB-003 may provide more selective binding information relative to PiB.
- CB-003 possesses a faster washout rate than 18F-PiB, which is consistent with consistent with the staining data: 18F-PiB requires harsher wash conditions in order to give reasonable grey to white matter ratios.
- the rapid washout of CB-003 is presumably a major factor for its low non-specific binding, yet the washout is slow enough to distinguish WT from APP.
- CB-003 being a neutral compound, would also potentially possess greater uptake values versus zwitterionic-based imaging agents such as methylene blue.
